Well done on sculpting
for a first time it's very promizing. you'll see that you 'll be more confident practicing sculpting.
Now you have to make a cool paint.
You can fix defects with a good paint, so if you need any advises, just ask
What painting technic will you use ? it seems that you started with a quite diluted coat of paint. Believe me, you don't need to make it so thin : you can go right out of the paint bottle. Diluting paint is usefull for special effects, or for very thick paints (paste tubes, for example). For tabletop rendering, you just can go with pure paint, and you'll see for dilution when you'll start the effects on skin.
tell me what you think about it,
